The specific embodiment

To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.

The utility model provides a kind of lock pressure device of tin furnace tool, sees also Fig. 1 to Fig. 4, comprises tool plate 1, lock pressing plate spare 2, lock pressure clip 3 and alignment pin 4.Wherein, product comprises pcb board A and high-order electronic component B.

Said tool plate 1 is provided with draw-in groove 101; Said lock pressing plate spare 2 is made up of fixed head 201, flexible member 202 and protection head 203; Said elasticity unit property 202 1 ends are connected with said protection head 203; The other end is connected with said fixed head 201, also is provided with locating hole 204 on the corner of said fixed head 201; Said lock presses clip 3 to comprise fixed part 301 and holding section 302 that the hinge connector through hinge pin 303 and wind spring (not shown) is connected; Said fixed part 301 is fixedly connected with said tool plate 1; Said holding section 302 flexibly connects with said fixed head 201; In present embodiment, be provided with 2 locks and press clip 3, be arranged at respectively on the said tool plate 1 corresponding two ends; Said alignment pin 4 upright being located on the tool plate 1, and with said locating hole 204 corresponding setting, in present embodiment, the quantity of said alignment pin 4 and said locating hole 204 is 4, is located at respectively on four corners of tool plate 1 and fixed head 201.In this, alignment pin 4 can be in the spacing fixed head 201 of living of vertical direction, and when flexible member 202 compressions, it is crooked to make that fixed head does not take place to side, and when assemble/when unloading, can be fast with fixed head 201 in alignment pin 4 upper sleeve throughs/take off.

In present embodiment, said flexible member 202 adopts springs, and in this, spring can be under high-order electronic component B height condition of different, and capturing position automatically forms suitable pressure and presses and attach high-order electronic component B.

In present embodiment, said protection head 203 is the cylinder of black plastic material, and it is stressed firmly that protection head 203 can protect high-order electronic component B to prevent, shields.

In present embodiment, 302 upper ends, said holding section comprise the last bent type working face 302a and following horizontal operation face 302b that comes in contact with said fixed head, and said bent type working face 302a of going up and said horizontal operation face 302b down make up and be the olecranon type.In this; When assembling, only need light press fit plate 201 downwards, the last bent type working face 302a effect of being under pressure of holding section 302 olecranon types upper end; Force the olecranon type upper end of holding section 302 pivoted laterally around hinge pin 303; Fixed head 201 is stuck between said down horizontal operation face 302b and the said fixed part 201 in the gap to bottom offset smoothly, and again owing to be provided with wind spring between fixed part 301 and the holding section 302, and the active force that offers fixed head 201 on the olecranon type of wind spring through holding section 302 offers the active force that fixed head 201 makes progress much larger than flexible member 202 (spring); Therefore, fixed head 201 is able to remain in this gap not and can be counter goes out; When needs take off fixed head 201, only need inwardly push the lower end of holding section 302, then open olecranon type upper end, can take out fixed head 201, and operation is very easy, quick.

In present embodiment, tool plate 1, draw-in groove 101, and lock pressing plate spare 2 be product and customize especially.Quantity and distribution that the pcb board A of the protection head 202 on the said lock pressing plate spare 2 and the quantity of flexible member 203 and distribution matching product goes up high-order electronic component B.

In sum, please continue to consult Fig. 1 to Fig. 4, after in the draw-in groove 101 that product A is placed tool plate 1; At first; With the fixed head 201 of locking pressing plate spare 2 up, its protection head 203 is butted on the high-order electronic component B of product A down, and locating hole 204 is set on the alignment pin 4; Secondly, push fixed head 201 downwards and force lock to press the olecranon type upper end motion laterally of clip 3 holding sections 301, fixed head 201 is fallen into down rapidly between horizontal operation face 302b and the said fixed part 201 in the gap, and quilt blocks and pushes down.Thus; Flexible member (spring) 202 is under high-order electronic component B height condition of different; Can form automatically suitable pressure and through the protection head 203 act on the high-order electronic component B; 4 spacing through alignment pin at last, press clip 3 to block press fit fixed head 201 through lock, on the basis that effectively the high-order electronic component B of protection is not damaged by pressure, make between high-order electronic component B and pcb board A that formation fits tightly fast; Product can be got into smoothly carry out soldering in the tin stove; Therefore, the utility model has effectively avoided high-order electronic component B generation rosin joint, empty weldering or inclination etc. when crossing the tin stove to cause the bad or loose contact of product appearance that processes, and effectively raises the production yield.
